This is a good article and an AMAZING video. Of course I was not around in 1967 when the program aired on 60 minutes but it is scary to think that a program like this would air on network tv. I would also guess that many people trusted 60 minutes. For some of that generation this might be where some of there views on 'gays' came from.
I really think you owe it to yourself to find the 45 min or so and watch the video It might help to understand why some have the view of gays that they do.
